Meshtastic Metrics Exporter

The meshtastic-metrics-exporter is a tool designed to export nearly all available data from an MQTT server to a Prometheus server. It comes with a pre-configured Grafana dashboard connected to both data sources, allowing users to start creating dashboards immediately.

Features

• Exports a comprehensive set of metrics from an MQTT server to Prometheus.
• Comes with a Grafana dashboard configured to connect to both Prometheus and Redis data sources.
• Stores node details (ID, short/long name, hardware details, and client type) in a Redis server, which is also part of the package.
• Configuration via a .env file.

Configuration

The project uses a .env file for configuration. Here is an example of the configuration options available:

# Description: Environment variables for the application

# Redis connection details
REDIS_HOST=localhost
REDIS_PORT=6379
REDIS_DB=0
REDIS_PASSWORD=

# Prometheus connection details
PROMETHEUS_COLLECTOR_PORT=9464
PROMETHEUS_JOB=example

# MQTT connection details
MQTT_HOST=172.232.220.244
MQTT_PORT=1883
MQTT_USERNAME=israeli
MQTT_PASSWORD=israeli123
MQTT_KEEPALIVE=60
MQTT_TOPIC='msh/israel/#'
MQTT_IS_TLS=false

# Exporter configuration
## Hide source data in the exporter (default: false)
MESH_HIDE_SOURCE_DATA=false
## Hide destination data in the exporter (default: false)
MESH_HIDE_DESTINATION_DATA=false
## Filtered ports in the exporter (default: 1, can be a comma-separated list of ports)
FILTERED_PORTS=0
## Hide message content in the TEXT_MESSAGE_APP packets (default: true) (Currently we only log message length, if we hide then all messages would have the same length)
HIDE_MESSAGE=false

Running the Project

To run the project, simply use Docker Compose:

docker-compose up --build

This command will build and start all the necessary services, including the MQTT server, Prometheus server, Redis server, and Grafana.

Grafana Dashboard

The project includes a Grafana dashboard pre-configured to connect to both the Prometheus and Redis data sources. This allows you to start creating and customizing your dashboards right away.
